' Be it known that I, EDGAR F. Inrcn, acitizen oi the e -'Unibcd S tat/es, residing at Niagara Falls, in the (ouiit I of Niagara and State of New York, have invented em '5 -tain new and useful Improyements in Lime Produet,.of

whichthe following is'a s peei fieation.

The quick-lime delivered from c'alcining kilns normally contains aer'msiderable amount of what is termed .overbui-nt lime a product which is highly-shrunk or irittcd, dense, hard and extremely resistant to hydratin'n or'slaking by wqter. It mortar or plaster be made from lime containing these overburnt portions, after such mortar or planter has been used and has set, the -alew slacking of the contained. articles of overburnt lime by the moisture of the atmosphere, with the muse quent; incream in volume due ti) hydration, causes defacts or fractures .tyhich seriously impair the strength 'and ap mr-(irice of the materiel. ..Fgr this reason the f overbumt lime is usually separated time the commerrial lime and thrown aside, or sold to tan-mom for appli- ..cation to'agriculturalland.

, I have found that when overburnt lime is ground or otherwise converted into an impalpuble wdenthe ilov vder readily alxsorbs water or hydmtes so that. it is I01 immediate une and has subs! :intiall y the same value as the beet commercial lime. This is presumably due to the (net. that the dense, highly-shrunk or silicions coating of the pztrliitles is abm led, broken or re- 'moved by grimling, so as to expose ultiniate portions whit-h areiu such physicalcondition as to readily absorb wan-r. The ground lime, however. is rapidly dl' 'tk-riomled by the action of damp air, so that. tors .4 12.

When properly packaged perfcmbly in't slwet -steel drums, it may be kept for long per ioda {1nd transported to any desi; -d point without undergoing dqterinmt'ien. r
